// Description:
// e32test\locale\t_currencyformat.cpp
// Overview:
// Test the currency formatting capabilities of the locale class.
// API Information:
// TLocale.
// Details:
// - Set the currency symbol position before the currency amount.
// - Set no space between the currency symbol and the currency amount.
// - Set 2 decimal places to currency values. 
// - Set negative currency value to be enclosed in brackets without a minus sign.
// - Allow triads in currency values.
// - Set comma as separator to separate groups of three digits to the left of the decimal
// separator.
// - Set dot as separator to separate a whole number from its fractional part.
// - Set currency symbol to pound.
// - Test some simple English Locale currency formats and check it is as expected.
// - Render a currency value as text, based on the locale's currency and numeric format 
// settings and check the Overflow handling capability is as expected.
// - Change a variety of locale settings and verify currency formatting is as expected.
// - Change a variety of locale settings display the results.
// Platforms/Drives/Compatibility:
// All 
// Assumptions/Requirement/Pre-requisites:
// Failures and causes:
